Chances are, you received a SIGPIPE. If not caught, that's a fatal
signal. (SIGPIPE occurs when you try to write to a socket that has
been closed by the other end.)

We currently have an SSL client/server setup that uses a basic "send
request, receive response" architecture. In one scenario, we did
something
similar to the following:
-----------------------------
Client:
1. Send request
2. Delete connection
Server:
1. Wait for connection
2. Process request
3. Send response
-----------------------------
The issue here was that the client never tried to receive a response
(since
it was unnecessary) and simply deleted the connection. However, the
server
was trying to send a response, even though the client closed the
connection.
We expected the SSL_write() function to handle such a scenario, returning
an
error code or something similar. However, it simply crashed. The last
line
of code that executes is the following:
int ret = SSL_write( ssl, &buffer[ bytesWritten ], length - bytesWritten
);
We know that bytesWritten is within the bounds of the 'buffer' array and
that 'length - bytesWritten' is always greater than 0. Therefore we
believe
the issue to be with SSL_write() itself. We are using OpenSSL 0.9.8.
Anyone ever run into something like this, or have any ideas on what might
be
happening? Any suggestions would be appreciated. Thanks
Dusty
